We found the divisors of 55, 786, 245, 102 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 55, 786, 245, 102 is 1.

Therefore, GCD of numbers 55, 786, 245, 102 is 1

Given Input Data is 55, 786, 245, 102

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 55 is 5 x 11

Prime Factorization of 786 is 2 x 3 x 131

Prime Factorization of 245 is 5 x 7 x 7

Prime Factorization of 102 is 2 x 3 x 17

The above numbers do not have any common prime factor. So GCD is 1

Step1:

Let's calculate the GCD of first two numbers

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(55, 786) = 43230

GCD(55, 786) = ( 55 x 786 ) / 43230

GCD(55, 786) = 43230 / 43230

GCD(55, 786) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 245

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(1, 245) = 245

GCD(1, 245) = ( 1 x 245 ) / 245

GCD(1, 245) = 245 / 245

GCD(1, 245) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 102

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(1, 102) = 102

GCD(1, 102) = ( 1 x 102 ) / 102

GCD(1, 102) = 102 / 102

GCD(1, 102) = 1

GCD of 55, 786, 245, 102 is 1
